This project provides for automatic control of the UPTIG process equipment using the UPTIG LIS developed by ZAO NPF Sistema-Service, together with the UPTIG ACS supplied as a set with the pulse gas preparation unit (UPIG).
UPTIG LIS provides the following functions:
• receiving analog and discrete signals from the UPTIG process equipment sensors;
• receiving data via standard interfaces:
- from the UPTIG ACS on the state of the UPTIG process equipment;
- from the Superflow-2E complex for measuring and recording the total gas flow rate;
- from the SG-EK complex for measuring and recording the gas flow rate for own needs;
• receiving from the LIS a command for an emergency shutdown of the UPTIG, issuing signals to the LIS on the operating and faulty state of the UPTIG;
• issuing warning and emergency settings;
• issuing control voltages of ±110 V to the valves;
• power supply for analog and discrete sensors ±24V;
• automatic rearrangement of the valve at the UPTIG inlet and the UPTIG candle valve during an emergency shutdown of the UPTIG;
• automatic rearrangement of the valves at the inlet of the fuel gas reducing threads;

• automatic rearrangement of the valves at the inlet of the gas reducing threads for own needs;
• automatic control of the UPTIG emergency exhaust ventilation;
• automatic transmission to the operator's workstation of the control center via interface communication lines of signals about the state of the UPTIG process equipment, its operating modes, the values ​​of the controlled parameters, the reception of control commands for the UPTIG process equipment.
In addition, the project provides for: monitoring of gas contamination in the UPTIG room:
• light and sound alarm for gas contamination of 10% of the LEL in the UPTIG room;
• automatic activation of exhaust ventilation in the UPTIG room at gas contamination of 10% of the LEL;

installation of push-button posts for activation of fire pumps, automation of the supply ventilation system P1.
